Catnic, a prominent manufacturer of steel building products, has introduced Solarseam, an innovative photovoltaic (PV) system specifically engineered for seamless integration with standing seam roofs. This new solution directly bonds flexible Copper Indium Gallium Selenide (CIGS) solar laminates onto Catnic’s urban standing seam roofing panels, offering a low-profile aesthetic combined with active energy generation. The launch marks a strategic move to enhance the renewable energy capabilities of the built environment, particularly as regulatory pressures for sustainable construction intensify.

Designed for remarkable versatility, Solarseam is compatible with roof pitches as low as five degrees, providing architects and developers with significantly increased design flexibility compared to conventional rigid solar panel installations. The system is delivered as a comprehensive kit, encompassing panels, flashings, and fixings, streamlining the ordering and installation processes for construction professionals.

At the core of Solarseam’s performance is its MCS-certified CIGS solar technology. Catnic highlights that these cells incorporate multiple diodes, which substantially enhance energy output in ambient light conditions and deliver superior shade tolerance compared to traditional monocrystalline panels. While shading can reduce energy output by up to 80% in monocrystalline systems, CIGS panels reportedly experience as little as a 10% reduction under similar conditions. Furthermore, the CIGS cells are characterized by their lighter weight, flexibility, and enhanced resistance to physical damage and cracking, contributing to the system's durability.

Emphasizing sustainability and local supply chains, Catnic states that the CIGS cells are manufactured in the UK, requiring less energy to produce than conventional monocrystalline alternatives, thereby contributing to a lower embodied carbon footprint. The urban standing seam panels, which serve as the substrate, are also UK-made and hold BES 6001 Responsible Sourcing certification alongside a BRE A+ environmental rating, underscoring the product's commitment to environmental stewardship.

Fire safety is a critical consideration for integrated building materials. The bonded panel system has undergone rigorous testing under CEN/TS 1187-4, achieving a BROOF(t4) classification. This represents the highest external fire rating under the standard, indicating minimal flame spread and no penetration for a minimum of 60 minutes, providing crucial assurance for building occupants and insurers.

Amanda Hinks-Edwards, Business Manager at Catnic, commented on the timely introduction of Solarseam, noting the UK government’s ambitious target for a 68% reduction in greenhouse gas emissions by 2030 and the strong indications that solar panels may become mandatory on all new homes from 2027. She asserted that Solarseam is well-suited for both new build and refurbishment projects, offering a compelling blend of solar performance, design adaptability, and aesthetic integration that aligns with evolving market demands and regulatory landscapes.
